Maltese in the Navy WW2

Newbie

I'm new to the forum and was hoping for a bit of info to help my research and writing on Malta during the Second World War. Any replies much appreciated!

Firstly, I'm wondering if anyone would have any insight into the recruitment of native Maltese into the Royal Navy either just before or during the war. Would there have been an active recruitment officer in Valletta, perhaps? The Maltese were mostly ratings, and I'm particularly interested in Officers' Stewards or similar.

Secondly, I've been searching in relation to the above, for the types of vessel which would have stewards as part of the crew? Would this have been limited to the larger vessels in the fleet or would it extend down to smaller ships such as minesweepers?
